UBI is just not happening any time soon in the US. To start, half of the country is already default against it. Precisely 0 people in Congress, the White House, or those in adjacent power roles (lobbyists and whatnot) are for it or have any idea what it is.

Aside from rolling out the guillotine, I don't see UBI a possibility until the 2nd half of the 21st century. There's just too many forces and entities alive that don't want it
